Smithey & Boynton, Architects & Engineers, was an architecture firm in Roanoke, Virginia, established in 1935 by Louis Phillipe Smithey and Henry B. Boynton. The firm closed during World War II for a few years while Boynton and Smithey served in the U.S. Army. After Smithey's death in the 1970s, Boynton partnered with Kenneth L. Motley, who began his career as a draftsman with the firm. In 1992, a year following Boynton's death, Motley acquired Smithey & Boynton and renamed the firm Motley + Associates.

Smithey & Boynton designed several structures over the years, including the Christ Episcopal Church, the South Roanoke Fire Station, the Shenandoah Life Building, McClanaham Street Office Building, and the American Theater Building, all in Roanoke. The firm also designed Lane Stadium at Virginia Tech and the Lyric Theatre in Blacksburg. The firm became best known for building public schools, even using the same basic layout for numerous schools. Smithey & Boynton had nearly 150 school design commissions during the period of 1945 thru 1953 in at least 19 counties and 10 cities.
